Source-code wise D is much leaner than C, obviously, but object-code wise it 
is *huge* even with dynamically linking Phobos:

The binary size of compiling my C version is 20271 and that of the D version 
with exact same functionality is 1031061. 

I thought maybe it's because I'm using a few ctRegex-es and that's getting 
included into the source code, but using ordinary regex actually increases 
the size to 1112343.

I suppose 1 MB is not a big deal these days, and if I cared about quick 
programming and not worry about buffer overflows, I have to sacrifice 
*something*, but still comparing to C, I can't help but feel that most of 
that 1 MB is functionality that the program never uses but I'm not expert 
enough to find out. If DMD had something like -fdata-sections -ffunction-
sections, passing --gc-sections might be able to slim that down, I dunno...
